Abstract: In the Arabian Sea surface salinity (S-O) is more than 35 PSU throughout the year, except in the southeastern regions. Increase of S-O in the central Arabian Sea during the summer monsoon season was mainly due to evaporation and vertical mixing of surface waters with subsurface high saline waters. Increased evaporation in the northern Arabian Sea due to low air humidity causes high surface salinity (>36 PSU) throughout the year. The subsurface maximum in the upper 200m corresponds to the Arabian Sea Watermass which lies on the 23.5 kg.m(-3) sigma-t surface. Large difference between surface and subsurface salinity maxima (>0.2 PSU during winter and summer monsoon) suggests the significance of surface dilution in the eastern Arabian Sea. Another feature in the vertical salinity structure is the transient multiple subsurface maxima separated by pockets of low saline water.
